We Stand by Our Services 100%


It is no coincidence that we’ve earned an “A” rating on Angie’s List and a 5–star rating on Yelp. Our customers are always satisfied, because all of our services are guaranteed 100%. That guarantee means that we agree to accept both personal and company responsibility for your complete 100% satisfaction with the operation of the equipment provided by us and paid for by you.

During the first year, if you are dissatisfied with the operation of the equipment we have installed, we will promptly correct the problem. If, after we do so, the equipment is still not operating according to the manufacturer’s standards, the manufacture representative has verified its failure and no other alternative is available, upon your written request we will remove the system and refund your money in full. This guarantee applies only to complete systems (such as a furnace, evaporator coil or condenser) installed on the same date and does not apply to any partial system installations. (Complete A/C or heating systems only: no partial systems. Some restrictions apply.)

In order to cover all of the bases, we also stand by our property protection guarantee. Under this guarantee, all property (such as lawns, shrubbery, carpeting, floors, walls, furniture and door frames) is protected, and damaged property will be replaced or repaired.
